Jeep Renegade won’t start – causes and how to fix it

Jeep Renegade Problems

The Jeep Renegade is one of the finest subcompact crossover SUVs on the market. Despite being small, this car is also great for off-road driving. However, it can be frustrating to find out that your Jeep Renegade won’t start because of one or two problems. Here are some of the common problems that cause the Jeep Renegade not to start and how to fix them.

Some of the problems that will cause your Jeep Renegade not to start are a dead battery, clogged fuel filter, failed starter, faulty electrical system, blown fuse, bad spark plugs, empty fuel tank, fuel pump failure, bad alternator, and corrosion on the battery.  

Why is my Jeep Renegade not starting? How do I fix the issue?

Dead battery

A dead battery is the first part that you should inspect if your Jeep Renegade is not starting. If the battery is dead or weak, it won’t supply electrical energy to all parts of the car. Therefore, you should have the battery checked before checking any other part.

This problem can be fixed by jumpstarting your car. If jumpstarting fails, this means the battery is dead and has to be replaced with a new one. You should change your car’s battery every three years. 

Failed starter motor

The starter motor turns the engine over during ignition and allows the car to start. Therefore, if the starter motor is bad or failing, the car won’t start. One of the common signs of a bad starter is a clicking sound. This problem can be fixed by replacing the bad starter motor with a good one.

Bad alternator

The alternator works hand-in-hand with the battery. The alternator is in charge of recharging the battery ad it keeps the car’s electrical system running after starting the car. So, if the alternator is bad or faulty, the car won’t start. Like a bad starter motor, a bad alternator will have to be replaced to fix the problem.

One of the common signs of a bad alternator is growling or whining noises.

Corrosion on battery

Corrosion on the contacts of your battery will stop the flow of current. As a result, you will try starting your car but it won’t start. If the current is not flowing, power won’t be delivered to your engine. To fix this issue, you will have to get rid of the corrosion on your contact and reconnect the battery.

Empty fuel tank

Having the right fluids in your car at all times is very crucial for the smooth operation of your car. It doesn’t matter if it’s engine oil, transmission fluid, or even fuel. If your car is out of fuel, it won’t start. It is vital to check your car’s fuel level before starting the car or taking off.

To fix this problem, you will have to refuel your car.  

Clogged fuel filter

If fuel cannot reach your Jeep Renegade’s engine, then the car will have a hard time burning it. As a result, the car won’t start. This is usually caused by a clogged fuel filter. Early signs of a clogged fuel filter are poor gas mileage and difficulty starting.

This problem can be fixed by unclogging the fuel filter. Besides, it is vital to service your car to avoid having such issues.

A blown fuse

Car fuses play a vital role in protecting the electrical wiring in your car from overcurrent and short-circuiting. So, if you have a blown fuse or if fusible links are damaged, the car won’t start. This is because power won’t reach the starter relay.

To fix this problem, you will have a professional mechanic inspect the car and find out whether the fuse is blown or the links are damaged. If the fuse is blown, it will have to be replaced. But if the links are damaged, they can be repaired.

Fuel pump failure

The fuel pump transfers liquid from the fuel tank to the carburetor or fuel injector of the internal combustion engine. If the fuel pump is failing, you will notice signs such as loss of power when accelerating, the car sputters at high speeds, and the engine won’t start. To fix this problem, you will have to replace the bad fuel pump.

Bad spark plugs

The spark plugs provide the spark that ignites the air/fuel mixture, forming the explosion that allows your engine to produce power. So, if the spark plugs are bad, your car will have trouble starting. And the only way to fix this problem is to replace the bad spark plugs with good ones.

Faulty electrical system

A faulty electrical system like loose or damaged cables can stop your car from starting. So, if you have checked all the above parts and your car won’t start, you should check your car’s electrical system and have the broken or damaged wires and connections fixed. This will avert the problem.
